As illustrated in FIG. 7, the guide main body 42 of the guide device 40is coupled to an inside of the drain pipe 50. The first guide vane 23 ofthe foreign matter catching prevention device 20 performs a liftingoperation in a state of being touched to or being in contact with oneside of the second guide vane 43 of the guide device 40 at a minuteinterval.

Since each of two of the three or more first guide vanes 23 performs alifting operation along one side of the second guide vanes 43 in a stateof being located in the same compartment space 44, stable lifting of thefirst guide vane 23 is possible. Specifically, since the first guidevane 23 performs the lifting operation in a state in which the firstguide vane 23 touches the second guide vane 43, the first guide vane 23can perform the lifting operation without being twisted.

Since the second guide vane 43 serves to guide the lifting operation ofthe first guide vane 23, the first guide vane 23 can perform a stablelifting operation without departing from a movement line without aseparate guide device.

Further, since the first guide vane 23 is located to overlap one side ofthe second guide vane 43, foreign matters such as hair discharged to thedrain pipe 50 together with water through a washbasin drainage flowsdown naturally along the first guide vane 23 and the second guide vane43, and thus, there is no fear of the foreign matter blocking the drainpipe 50. In addition, since the first guide vane 23 moves whileperforming the lifting operation, foreign matters such as hair can bedischarged more smoothly along the drain pipe 50.

Further, since water discharged to the drain pipe 50 flows to the centerof the drain pipe 50 along the lower portion 422 of the conical guidemain body 42, the drainage can be made more smoothly.

Further, in the pop-up valve according to the embodiment of the presentinvention, the head portion 10 and the foreign matter catchingprevention device 20 can be easily disassembled and assembled throughthe pop-up rod 30. Further, since there is no gap between the headportion 10 and the protruding jaw 22 because an upper surface of theprotruding jaw 22 of the foreign matter catching prevention device 20 isin close contact with the sealing member 12 of the head portion 10,there is no fear of foreign matters being caught.

As described above, in a pop-up valve according to the embodiment of thepresent invention, a first guide vane of a foreign matter catchingprevention device is located on one side of a second guide vane of aguide device, and thereby, foreign matters such as hair dischargedtogether with water to a drain pipe can flow down naturally along thefirst guide vane and the second guide vane without being caught by thesecond guide vane. Further, since the first guide vane performs alifting operation in a state of being touched to the second guide vane,the first guide vane can perform a stable lifting operation withoutdeparting from a movement line.
